Air tightness training course to launch in Carlow this March

Peaky blinder

From frozen tea to thermal bliss: energy specialist Esmond Tresidder transformed his leaky 1970s Highland home into one of the highest performing retrofits ever featured in these pages, combining academic knowledge with hands-on retrofit innovation to create a comfortable, healthy family haven with breathtaking views of Ben Nevis, proving that even Scotland’s most challenging climates are no match for passive house principles.

History repeating

Retrofit redux: Catching up with A3

The upgrade of Ireland's retrofit target to A3 marks a critical step forward, bridging the gap between energy modelling and real-world performance, explains Dr. Marc Ó Riain.

Energy poverty and electric heating

As electricity decarbonises, the case for switching from fossil fuel boilers to efficient use of electricity to heat buildings via heat pumps has become overwhelming.
